That is correct. In Omniture’s tools, you can create a segment at the page, visit or visitor level. Adam Greco is a part of the best practices group at Omniture and in fact posted a blog entry about Omniture’s segment builder earlier this week:

I managed to get access to GA advanced segmentation relatively quickly and I was working at Nedstat when they released their advanced segmentation. Both systems are remarkably similar except that GA is based solely on visits while Nedstat only allows you to segment at visitor level – both systems being restrictive as a result.

What I would like to do with either is first specify the level at which I am setting the segmentation – visitor, visit or page view (event) and then create the segment. It appears from what you have written that this is how it works with Omniture Discover – is that correct?
